@ Jack,
I think segregation is part of human nature. People somehow cuddle together in their own group, that they perceive as best. It gets worse when fear of the other groups gets stronger. And worse when some of the groups has more power than the other groups, also about those other groups.
Your way out of the racism thoughts in your head was a personal one. Telling nothing about what sociologically is a reality. But it did liberate you in your head. It gave you personal freedom. I will not dispute that, nor make that smaller than it is. It is a great thing to have.
It does not take away the reality of there being lots of people targeted as second class citizens; because of race, origin, history, social layer, religion or what ever.
When SG wrote about a neighbourhood being taken over, it made me think about modern neighbourhood improvement programs. Put in creative students in a neighbourhood with a bad name. Let them do some community work in exchange for lower rents. Get some fashionable restaurants in that neighbourhood. And other people will come in. The bad vibe of the area will disappear. And things will get better. So far, so good. But then the area grades up, becomes a place people want to live, because it is trendy, rents and the prices of houses go up, more expensive shops come in. And it becomes unaffordable to live in for a lot of the original inhabitants. And they have to move. Not only losing their house, but also the social setting they lived in, so, losing their social network.
Wolfie and SG tell things from their lives that show a social injustice. You show a psychological liberation. That is not a liberation on a sociological level, but it has freed you and given you space to be who you are. What I read from Wolfie and SG, they have a similar psychological freedom, but they are very aware of the social setting they live in and are determined by in their daily life too. And it is something that needs to be targeted and needs to be seen. Segregation will happen. People are different and will flock together in groups they feel secure in. But it should not come with such stigmatisation nor such differences in power.
